Using HeavyM with video wall controller

I'm trying to use HeavyM with a 2 x 2 video wall controller (Orei UHP-202VW) to send one video to 4 projectors (each projector will show 1/4 the video).  I set up 4 screens on the canvas and gave each one the resolution of one of the projectors.  When I try to assign the 4 screens to the 4 projectors, I only have one option to choose from, the controller.  If I assign the first screen to the controller, it changes the resolution from the projector resolution I had setup.  If I try to assign the second screen to the controller, I get a message indicating that the first screen is already assigned to the controller and do I want to assign the 2nd one instead. So I can't assign them all to the controller, nor can I assign them to individual projectors.  If I set the Output to fullscreen and choose the controller, I can see the test card across the 4 projections but not on my computer screen.  If I select Output setup, I can see and manipulate the 4 screens on the computer but can't see the manipulations in the projections.  So I don't see any way to warp or edge blend the content because I can never see them on the computer screen and in the projections at the same time.  Is this because of any incompatibility between HeavyM and the controller or am I doing something wrong?  This is my first time using the software.  Also, if it is a compatibility issue, is an MST hub a better option?  Are there compatibility issues there that I should be aware of?  Thanks

  Hello P Georges,

  Firstly, we truly appreciate the effort and creativity you're putting into setting up your projection mapping project with HeavyM. We understand that working with a 2 x 2 video wall controller presents its unique set of challenges, and we're here to guide you through the process.

  Regarding your setup with the Orei UHP-202VW video wall controller, it's important to note that HeavyM perceives the controller as a single screen rather than separate outputs. This means that the software sends one large frame to the controller, which then divides the video signal across your projectors. Because of this, HeavyM's output setup window won't allow for individual screen control for warping or edge blending directly.

  However, there's a workaround to achieve the desired effect within the canvas itself. You can use four different players to play the same video source but crop each one to a quarter of the video. This way, you can individually warp each player using the player options in the properties panel on the left side of the user interface. While this method doesn't support blending, it allows for precise control over the warping of each section.

  As for the MST (Multi-Stream Transport) hub, it could be a viable solution if it allows HeavyM to recognize and control each output separately in the output setup window. If the MST hub behaves similarly to your current controller, you might encounter the same limitations.

  We hope this guidance helps you move forward with your project. Please don't hesitate to share your progress or reach out if you have any more questions or run into further issues. We're here to support your creative endeavors with HeavyM and ensure you achieve the best possible results.
